I know its apples and oranges but I recently redid my entire house garage (cabinets, tool boxes, storage, etc. etc.). At first I was overwhelmed and struggled but really got a handle on things by spending A LOT of time at the various stores just looking at the toolboxes and storage options. There really are a lot of great affordable boxes and containers.
Only you know what tools you have and how often you use them so it's tough for a bunch of strangers to design your space. To some people a set of tools consists of two screwdrivers, a set of pliers and a roll of duct tape. Other RVers are retired race car mechanics and carry enough tools to rebuild an engine.
